Materials Data on PPbO3 by Materials Project
PbPO3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.43–3.26 Å. In the second Pb2+ site, Pb2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Pb–O bond distances ranging from 2.35–2.72 Å. In the third Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.56–3.07 Å. There are three inequivalent P4+ sites. In the first P4+ site, P4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.55 Å) and one longer (1.56 Å) P–O bond length. In the second P4+ site, P4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. In the third P4+ site, P4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one P4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P4+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P4+ atom.
